Description

Filter Cap for Liquid Base Cytology

The present invention relates to a filter container used in a sample processor for liquid cytology, and more specifically, to a filter cap for liquid cytology that is provided so that the sealed portion of the container for conducting the test can be opened and closed, thereby enabling reuse and preventing the internal solution from leaking even after dispensing.

Typically, in liquid-based cytology, cells are collected from the area of the body being examined to check for cancer and disease, and the collected cells are preserved in a preservation reagent container before being transported to a screening center.

Afterwards, foreign substances in the specimen are removed using a sample processor and a disposable filter cap, the cells and materials required for the test are attached to a slide glass, and then the staining step is performed to read the abnormal condition of the cells under a microscope to determine the presence or absence of cancer or disease.

According to this method, before injecting the sample contained in the preservation reagent into the filter container, the preservation reagent container is shaken by hand or a separate stirring device is used to disperse the cells and foreign substances in the clumped sample.

Afterwards, open the lid, pour the sample into the filter container, and attach the suction device to the bottom of the filter to suck up the sample. Mucus and foreign substances are filtered out from the primary mesh attached to the filter cap, and the cells collected on the membrane with pores of 5 to 10 μm are attached to the slide glass. However, a sample with a lot of mucus and foreign substances can clog the primary mesh, so the poured sample cannot be sufficiently sucked up and remains in the filter container.

When the filter container is separated to allow access to the membrane through which the cells are filtered to the slide, the remaining mixed liquid that cannot be sucked up falls down by gravity and is lost.

In addition, since the process of attaching cells from the preservation reagent container to the slide glass must be done manually by the user one by one, it takes a lot of time, and since the user must determine the injection amount according to the sample concentration, a large amount of sample is lost, and since the lid must be opened and the sample poured, there is a problem that contaminants or impurities can be transferred from the user's hand to the slide glass, which reduces the accuracy of the cell test.

In this way, the filter cap for liquid cell smear of the prior art has a container containing a specimen consisting of preservation reagent and cells for smearing on a slide glass, a filter for removing mucus and foreign substances from the specimen in the container and collecting cells and necessary substances, and a smear device for smearing the cells collected in the filter on the slide glass, each independently separated, and there was a problem in that the device took up a lot of space due to errors caused by manual work such as opening and closing the preservation reagent cap, injecting the specimen, mounting the filter, and separating the filter, and the device had to be moved to each position.

The filter described above has a problem in that the user must pour the sample according to the concentration of the sample in order to filter by injection of the sample. If too little is poured, not enough cells for examination are collected. If too much concentrated sample is poured, the mesh of the filter becomes clogged with mucus and foreign substances, preventing suction and causing loss.

Accordingly, a technology has been developed and used recently to collect liquid cells by inserting a collection portion that is sealed in the center of an open side of a container containing a specimen, has a lid-shaped opening body with a filter installed inside, moves in a sealed state, and then breaks the seal in the shape of a needle to collect the liquid cells.

The filter container of the above-described prior art has the advantage of being hygienic by maintaining a sealed state, and minimizing contamination by collecting in a filtered state while releasing the seal during collection.

However, the filter container of the prior art had a problem in that it was difficult to use after a single sampling due to contamination, as sampling was performed by destroying the sealing part.

In addition, since the filter container of the prior art must have a sharp needle-shaped sampling portion to break the sealing portion, there is a risk of injury to the worker due to contact during sampling.

The present invention has been made to solve the above-mentioned problems, and the purpose of the present invention is to provide a filter cap for liquid cell smear, which can be used multiple times by having a sealing portion of a container in which liquid cells of a filter container used in a specimen processor for liquid cell examination are contained in a solution state and opened by pressurization, and closed and maintained in a sealed state while returning to the original position after collection, and which has a collection portion that opens by pressurization, so that it does not need to have a sharp shape, thereby reducing the risk of injury.
